Texas Halo Fund led a Houston startup's seed round last month. Galen Data, which uses its cloud-based software to connect medical devices, closed a $1 million seed round thanks to the fund's $250,000 investment. Kevin King, one of Texas Halo Fund's managing director, has also been named to the startup's board of directors.

According to the release, the Texas Halo Fund based its decision for the investment "on the large and growing addressable market of connected medical devices, the company's impressive management team, and post revenue status."

Galen Data's emergence comes as the market for internet-connected mobile health apps keeps growing. One forecast envisions the global space for mobile health exceeding $94 billion by 2023.

"We want to be at the forefront of that technology curve," DuPont tells InnovationMap in a previous interview. "We might be six months early, we might be a year early, but it's starting to happen."

SurfEllent, an anti-icing coating technology startup founded out of the University of Houston has raised $470,000 in funding. The company won the second place award and a total of $45,000 at the Texas A&M New Ventures competition before receiving an anonymous investment of $350,000 in seed funding. SurfEllent also received two grants: a $50,000 Small Business Innovation Research grant and a $24,999 Small Business Technology Transfer grant.

"Ice is a problem that will exist as long as we live on the earth. It impacts a wide range of things, including aircraft wings and engines, automobiles, buildings and bridges, ships and vessels, and power transmission systems," says SurfEllent Co-Founder Hadi Ghasemi, a Bill D. Cook Associate professor of mechanical engineering at the UH Cullen College of Engineering, says in a news release.

SurfEllent's product can be used in the de-icing of cars and airplane engines.

"The end goal is to improve the quality of human life," Ghasemi says in the release. "This recognition is another proof of the critical need for advanced anti-icing coating technologies and opens opportunities for collaboration with various industries and business partners."

Cemvita Factory

In August, Occidental Petroleum's Oxy Low Carbon Ventures LLC invested in Houston-based Cemvita Factory, and in September, BHP followed suit. While Cemvita Factory isn't able to disclose how much money its raised through these partnerships, the company confirms it has closed its round of funding.

Cemvita Factory is run by a brother-sister team. Moji and Tara Karimi built the company off of Tara's research into mimicking photosynthesis. The process is able to help reduce energy company's carbon emissions.

"We have an ambitious goal to take one gigaton of CO2 out of the carbon cycle in the next decade and are very excited about being a part of Occidental's journey to become a carbon-neutral company," says Tara, co-founder and chief scientist, in a news release.

The investments will help Cemvita Factory continue to develop its biomimicry technology for oil and gas applications to reduce the volume of greenhouse gas emissions.

Sourcewater

Houston-based Sourcewater Inc., which specializes in oilfield water intelligence, closed its series A round at $7.2 million. Bison Technologies, Marubeni Corp., and major energy family offices in Houston, Midland, Dallas, and Oklahoma City contributed to the round. The funds will go toward further developing the company's technology.

"For every barrel of oil produced in the Permian Basin there are more than ten barrels of associated water that are sourced, recycled, transported, and disposed of," says Joshua Adler, founding chief executive of Sourcewater, in a news release. "When America became the world's leading energy producer last year, it also became the world's leading water producer, times ten. Water management is now the majority of upstream energy production cost, and water sourcing, recycling and disposal capacity is the primary constraint on America's energy future."

SEATz

Houston startup sEATz has created a platform where fans can order just about anything their stadium has from an app. Much like any other ordering app, once the order is placed, a runner will pick up the food and deliver it to the customer for a small fee and a tip.

The startup is now preparing to scale up from seven venues to 10 before the year is over as well as launching a new version of the app thanks to an oversubscribed near $1.3 million seed round led by Houston-based Valedor Partners. Houston-based Starboard Star Venture Capital also contributed to the round. SEATz has plans to launch its Series A round before the new year.

"We're building enterprise-level, scalable in-seat ordering, delivery, and pick-up software. We'll have all the data and validation we need this fall to really start to push that out," says CEO and co-founder Aaron Knape.

Syzygy

Using research that came out of Rice University, Syzygy Plasmonics has developed a hydrogen fuel cell technology that produces a cheaper source of energy that releases fewer carbon emissions.

The company just closed a $5.8 million Series A round led by MIT's The Engine and Houston-based The GOOSE Society of Texas. Evok Innovations, a previous investor in the company, and angel investors from the Creative Destruction Lab also contributed to the round.

"We're starting to solidify relationships and get customers ready," CEO Trevor Best tells InnovationMap.

Topl

Houston-based Topl, a blockchain network with applications across industries, closed a 20 percent oversubscribed $700,000 seed round.

"Every investor that is invested now has focused on both the purpose and the profit, and I'm big on that," Kim Raath, president and co-founder of Topl, says.

The team has built six blockchain platforms that operate on the Topl network — two are live now, and four will go live later this year. The platforms are focused on four different areas: agriculture (tracking food products from the farm to the shelves), mining (diamonds, for instance), sustainability and impact (tracking a program to see how it succeeds), and carbon credits and renewables within the energy industry.

fresh funding

Editor's note: This article has been updated to clarify information about Cart.com's investors.

Houston-based commerce and logistics platform Cart.com has raised $180 million in growth capital from private equity firm Springcoast Partners, pushing the startup past the $1 billion funding mark since its founding in 2020.

Cart.com says it will use the capital to scale its logistics network, expand AI capabilities and develop workflow automation tools.

“This investment will strengthen our balance sheet and provide us with the flexibility to accelerate our strategic priorities,” Omair Tariq, CEO of Cart.com, said in a news release. “We’ve built a platform that combines commerce software with a scaled logistics network, and we’re just getting started.”

In conjunction with the funding, Springcoast executive-in-residence Russell Klein has been appointed to Cart.com’s board of directors. Before joining Springcoast, he was chief commercial officer at Austin-based Commerce.com (Nasdaq: CMRC). Klein co-led Commerce.com’s IPO, led the company’s mergers-and-acquisitions strategy and played a key role in several funding rounds.

“The team at Cart.com has demonstrated excellence in their ability to scale efficiently while continuing to innovate,” Klein said. “I’m excited to join the board and support the company as it expands its AI-driven capabilities, deepens enterprise relationships, and further strengthens its position as a category-defining commerce and fulfillment platform.”

This is the income required to be a middle class earner in Houston in 2026

Cashing In

A new study tracking the upper and lower thresholds for middle class households across the nation's largest cities has revealed Houstonians need to make at least a grand more than last year to maintain their middle class status this year.

According to SmartAsset's just-released annual report, "What It Takes to Be Middle Class in America – 2026 Study," Houston households need to make anywhere from $42,907 to $128,722 to qualify as middle class earners this year.

Compared to 2025, Houstonians need to make $1,153 more per year to meet the minimum threshold for a middle class status, whereas the upper bound has stretched $3,448 higher. The median income for a Houston household in 2024 was $64,361, the study added.

SmartAsset's experts used 2024 Census Bureau median household income data for the 100 biggest U.S. cities and all 50 states and determined middle class income ranges by using a variation of Pew Research's definition of a middle class household, stating the salary range is "two-thirds to double the median U.S. salary."

In the report's ranking of the U.S. cities with the highest household incomes needed to maintain a middle class status, Houston ranked No. 80.

In the report's state-by-state comparison, Texas has the 24th highest middle class income range. Overall, Texas households need to make between $53,147 and $159,442 to be labeled "middle class" in 2026. For additional context, the median income for a Texas household in 2024 came out to $79,721.

"Often, the expectations that come with the term 'middle class' include reaching home ownership, raising kids, the comfort of modest emergency funds and retirement savings, and the occasional splurge or vacation," the report said. "And as the median household income varies widely across the U.S. depending on the local job market, housing market, infrastructure and other factors, so does swing the bounds on what constitutes a middle class income in America."

What it takes to be middle class elsewhere around Texas

Two Dallas-Fort Worth suburbs – Frisco and Plano – have some of the highest middle class income ranges in the country for 2026, SmartAsset found.

Frisco households need to make between $96,963 and $290,888 to qualify as middle class this year, which is the third-highest middle class income range nationwide.

Plano's middle class income range is the eighth highest nationally, with households needing to make between $77,267 and $231,802 for the designation.

Salary range needed to be a middle class earner in other Texas cities:

No. 28 – Austin: between $60,287 and $180,860
No. 40 – Irving: between $56,566 and $169,698
No. 44 – Fort Worth: between $55,002 and $165,006
No. 57 – Garland: between $50,531 and $151,594
No. 60 – Arlington: between $49,592 and $148,77
No. 61 – Dallas: between $49,549 and $148,646
No. 73 – Corpus Christi: between $44,645 and $133,934
No. 77 – San Antonio: between $44,117 and $132,352
No. 83 – Lubbock: between $41,573 and $124,720
No. 84 – Laredo: between $41,013 and $123,038
No. 89 – El Paso: between $39,955 and $119,864
